Density values in voxi unusual

EssamAboud

Dear Voxi user

I am new user in Voxi earth modeling and have some questions about it.

I have gravity data for inversion. I only have topo data to be used for sensor elevation as well as DEM grid, am I right?

Normal unconstraint inversion give me voxel file (V1) with data values as -46 to 23.7. Is that normal density or something else.

I did create Gradient weight using from V1 in EW, NS, and Vertical Gradient (VG). The three voxel files has ranges from 0 to 1 as data range......... I am still confused.

I summed the EW, SN, and VG voxi files to get Gradient Reference Model (GRM). it gives me new file with data range as 0 to 3... how it comes?

I used the above mentioned voxel files (EW, NS, and VG) to be constraint in the inversion, it give me new file with data as -685 and 2768.......... I expect to have density values less than that........

I guess there may be mistake, your help will be appreciated.
